Region(s) East Africa

Mngwa is a cryptid felidae said to dwell along the coasts of East Africa, the name having been introduced into popular Western use by a British colonial administrator, Captain William Hichens, who, in 1937, reported to the journal Discovery on local belief regarding the creature, describing it as "a gigantic cat, striped like a tabby, but as large as a donkey and far more ferocious and fearsome than any lion" that was blamed for the deaths of villagers during periodic raids.
